in the end I managed to solve. The problem was the crappy router of my operator (router a) that I connected in cascade with the Fritzbox. It acted as a filter ...
I solved this way.
I enabled the DMZ host by the router A in the Fritzbox (b router)
I have enabled the port 5001 in the router A, at 192.168.1.4 (where you connected the router B)
I enabled the Fritzbox the port 5001 in 192.168.178.10 (WServer 2012 r2, where the server and installed HFS) is connected
EVERYTHING WORKS AT LAST!
THANK YOU ALL!
